Osoba said that people do not need to be sick before going for regular checkup.“Most of the patients only come to the hospital for late presentation when they can barely see, which means 80 per cent of the vision are lost.

“There is need for more constant sensitisation of people on glaucoma by health organisations and the government, because nobody knows when glaucoma will develop in the eye.

“Blindness can also be prevented, if there is early detection of glaucoma through proper screening and regular eye examination.

“Glaucoma week is to create awareness to the public about this disease called glaucoma, because it is a serious disease and silent thief of vision.
